at scala.collection.mutable.AbstractMap.getOrElseUpdate(Map.scala:91) Could you please advise how to overcome the error? Reply. Valentin Nikotin. February 21, 2017 4
Cause. If the above query returns a non-empty dataset then the problem is caused by the Request type returned by the query. Resolution. Remove these request types or add at least one field to the request type.
Package structure . The scala package contains core types like Int, Float, Array or Option which are accessible in all Scala compilation units without explicit qualification or imports. Notable packages include: scala.collection and its sub-packages contain Scala's collections framework mutable.HashMap getOrElseUpdate not reentrant in 2.12 Showing 1-3 of 3 messages. [scala-user] mutable.HashMap getOrElseUpdate not reentrant in 2.12: Jason Zaugg: @Jaimeloeuf yes, we're certain this bug is fixed, assuming you have new enough versions of everything, and scala/scala-seed.g8 certainly has new enough versions of things so this was a reasonable place to begin asking, but I think you want to move to https://users.scala-lang.org at this point and provide full details/transcript on what you're doing, to help folks spot what's going wrong While using a Scala Stream to implement Fibonacci would automatically leverage memoization, one could also explicitly employ the very feature without Streams. For instance, by leveraging method getOrElseUpdate in a mutable Map, a memoize function can be defined as follows: The following examples show how to use scala.collection.mutable.Map.These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

outputs look fine, I noticed java13 wasn't listed on scala page, decided to look into scala PKGBUILD and found this : depends=('java-environment=8' 'java-runtime=8') Try switching to java8 as default.

This is the documentation for the Scala standard library. Package structure . The scala package contains core types like Int, Float, Array or Option which are accessible in all Scala compilation units without explicit qualification or imports.
Avoid lambda allocation in getOrElseUpdate call Avoid intermediate Tuple2 instances when iterating through the mutable map. Avoid allocating Map1-4 during building the result if the size of the grouped exceeds 4. This is the documentation for the Scala standard library. Package structure .
ms -= (k, l, m) Removes mappings with the given keys from ms as a side effect and returns ms itself. ms --= ks
// not possible with Int counts.getOrElseUpdate(key, 0) += 1 // but with a modifiable counter counts.getOrElseUpdate(key, new Counter).increment Somehow I'm always expecting to have the following functionality with a mutable map (somewhat similar to transform but without returning a new collection and on a specific key with a default value):
Note: getOrElseUpdate is not an atomic operation in EhCache and is implemented as a get followed by computing the value, then a set.

The factory creates 'Some(x)' if the argument is not null, and 'None' if it is null. The 'getOrElse(Default)' method goes into the Scala class hierarchy… Return optional values from a function with the Option class.
